CentOS 7.4源码安装Cacti 1.1.26监控Linux主机图文详解
记录在CentOS 7.4下源码安装Cacti 1.1.26图文详解,希望对大家有所帮助。
此实验需要联网,所以要两块网卡,一块仅主机,一块桥接
所需软件压缩包

mysql_secure_installation 安全配置向导
初次运行直接回车
是否设置root用户密码,输入y并回车或直接回车
设置root用户的密码
再输入一次你设置的密码
是否删除匿名用户,生产环境建议删除,所以直接回车
是否禁止root远程登录,根据自己的需求选择Y/n并回车,建议禁止
是否删除test数据库,直接回车
是否重新加载权限表,直接回车(这一步上图没有截全)
vi /var/www/html/index.php //编辑网页测试文件
<?php

测试,在浏览器中输入192.168.80.100
如上图,表示httpd和php已正常启动,并连接成功

测试检测mysql 与php是否协同工作,在浏览器中输入192.168.80.100
如上图所示,表示mysql 与php正协同工作
安装cacti
tar xf cacti-1.1.26.tar.gz
mv cacti-1.1.26 /var/www/html/cacti
mysql -ucacti -p cacti < /var/www/html/cacti/cacti.sql
mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -uroot mysql -p
mysql -u root -p
grant select on mysql.time_zone_name to 'cacti'@'%' IDENTIFIED BY 'admin123';
//在数据库中为时区文件授权
flush privileges;
vi /var/www/html/cacti/include/config.php
$database_username = 'cacti';
$database_password = 'admin123';
配置SNMP
vi /etc/snmp/snmpd.conf
com2sec notConfigUser 127.0.0.1 public //改成环回口地址 41
access notConfigGroup "" any noauth exact all none none //把systemview改成all 62
view all included .1 80 // 去掉#号 85
systemctl restart snmpd.service
systemctl enable snmpd.service
useradd -r -M cacti
chown -R cacti /var/www/html/cacti/rra/
chown -R cacti /var/www/html/cacti/log/
chown -R apache.apache /var/www/html/cacti/resource/
chown -R apache.apache /var/www/html/cacti/cache
chown -R apache.apache /var/www/html/cacti/scripts
crontab -e
/5 * /usr/bin/php /var/www/html/cacti/poller.php >> /tmp/cacti_rrdtool.log
安装cacti-spine优化数据轮询速度
ln -s /usr/lib64/libmysqlclient.so.18.0.0 /usr/lib64/libmysqlclient.so
tar xf cacti-spine-1.1.26.tar.gz
cd cacti-spine-1.1.26
./configure && make && make install
cp /usr/local/spine/etc/spine.conf.dist /usr/local/spine/etc/spine.conf
vi /usr/local/spine/etc/spine.conf //修改相关参数
DB_Host localhost
DB_Database cacti
DB_User cacti
DB_Pass admin123
DB_Port 3306
RDB_Host localhost
RDB_Database cacti
RDB_User cacti
RDB_Pass admin123
RDB_Port 3306
systemctl restart httpd
systemctl restart mariadb

安装步骤:
输入账号admin和密码admin
重设密码,密码为大写小写特殊字符组合,如Abc123a,
Console -> 设置(Cacti Settings) -> Poller -> 在 Poller Type 下拉框中选择 spine ,点击保存 (Save)。注意:假如使用spine的话,下面两项轮训时间和计划任务间隔时间都要设置为every Minute
在添加完设备和图形后,需要重建采集器缓存。
去cacti上查看
管理设备(device)
查看linux状态为UP即可,注意不要着急spine方式刚刚启动需要2-5分钟左右时间,有快有慢
设置主机的IP地址:设备——>点击local linux machine
然后直接选图形,可以查看cacti处理后的图片
如上图所示,cacti正在监控Linux主机。
